OpenURL and SFX Linking

Abstract

It is only a few short years since the early academic research led by Herbert Van de Sompel at Ghent University in Belgium that resulted in the formulation of the OpenURL standard and the development of the SFX link server. These complementary components have revolutionized linking for libraries, putting control for linking in the hands of the librarian.

This paper considers briefly the early linking initiatives, explains the purpose and structure of the OpenURL and the role of linking components-the sources, targets, and the link server, with a focus on the SFX link server.     

OpenURL与无缝链接

NISO's IOTA Initiative: Measuring the Quality of OpenURL Links

The Improving OpenURLs Through Analytics (IOTA) initiative was formed by the National Information Standards Organization (NISO) in 2010 to continue a Mellon-funded project on OpenURL quality begun at Cornell University. IOTA's objective is to develop a scoring system for measuring the quality of OpenURL links generated by content providers at the citation level. OpenURLs have a history of failing to resolve correctly, but no method has been devised to benchmark them even a decade after the introduction of the underlying standard. The proposed system would generate scores based on specific evaluation metrics and thus rate providers' OpenURL quality. The system's analytical approach would also enable OpenURL providers to pinpoint linking problems and thus optimize OpenURL improvements. A public OpenURL analysis tool, which relies on link data contributed by OpenURL providers and libraries, is currently in use. Recently, IOTA approached the Knowledge Bases And Related Tools (KBART) initiative about a possible collaboration on a related project, which would investigate OpenURL linking not at the citation level, but the full-text level.

A comparison of OpenURL link resolvers: The results of a University of Connecticut Libraries environmental scan

Open URL link resolvers are emerging technological tools designed to increase use of library collections by automating the process of locating and accessing library holdings. This study examines the system architecture and capabilities of commercially available OpenURL link resolvers to assess viable options for the University of Connecticut Libraries. Data for the study, largely experiential feedback received from libraries employing OpenURL link resolvers, were gathered through a series of evaluative activities. These included a preliminary literature review, Web survey, follow-up e-mail survey, and on-site visits to libraries. Results were analyzed within the context of the University of Connecticut Libraries' resources and needs. Analysis revealed wide variation in library experiences with and perception of product functionality and performance, as well as requisite staff and financial investments.

Improving E-Book Management,Discovery, and Access: Two New NISO Initiatives Get Working

E-books play an important role in library collections; however, the sheer number of books and the nature of access models, such as limited simultaneous use, create some significant challenges for their discovery and access. For this column we asked Nettie Lagace from the National Information Standards Organization (NISO) to tell us about some of the work NISO has been doing in this area and highlight some of the initiatives designed to provide more interoperability among parties in the e-book supply chain.     

PIE-J for Improving Access to e-Journal Content

Successfully connecting users to content in an online environment demands a high level of accuracy in the information eco-system. However, journal titles change names and International Standard Serial Numbers (ISSNs). When publishers, subject indexes, link resolvers, or other parties involved in connecting users to content fail to accurately represent the original details of cited articles, links fail, content becomes inaccessible except to very accomplished and determined librarians, and users become frustrated. The PIE-J (Presentation and Identification of E-Journals) offers a simple and common-sense set of recommended practices and guidelines for publishers and content providers to follow to standardize the presentation and identification of e-journal content.
